Micropterus salmoides mixed feed with yeast hydrolysate replacing fish meal

The invention provides a micropterus salmoides mixed feed with yeast hydrolysate replacing fish meal. The micropterus salmoides mixed feed comprises 15-22 percent of the fish meal, 10-15 percent of pea protein powder, 10-15 percent of bean pulp, 1-5 percent of krill powder, 10-15 percent of gluten, 1-5 percent of phospholipid, 5-10 percent of fish oil, 1-5 percent of premix, 15-25 percent of flour, 1-5 percent of wheat middling, 0.5-3 percent of lysine, 0.1-1 percent of methionine, 0.1-1 percent of threonine and 1-8 percent of the yeast hydrolysate. The use amount of the fish meal is decreased, the cost is reduced, and the economic benefit of a farmer is increased; in addition, the ratio of liver weight and body weight can be reduced, and the intestinal and liver functions of micropterus salmoides are improved.
